The bicycle [3.1.0] hexane ring system is found in natural products like sabinene in black paper. The mechanism of the preparation of this molecule is to be interpreted from compound 1 to compound 3. Concept Introduction: Alkenes or cycloalkene are unsaturated hydrocarbons. These hydrocarbons have at least one double covalent bond between the carbon atoms. The presence of the π bond makes it unsaturated and tends to give the addition reactions. The addition of electrophiles is the most common chemical reaction of alkene as the presence of π bond makes alkene electron-rich molecules.

Answer 1

Question

Definition Definition Molecules that have multiple bonds between their carbon atoms. Alkenes are hydrocarbons with a double bond between two adjacent carbon atoms (R 2 C=CR 2 ), whereas alkynes are hydrocarbons with a triple bond between two adjacent carbon atoms R-C=C-R . These two groups are known as unsaturated hydrocarbons. They have fewer hydrogen atoms when compared with alkanes with same number of carbon atoms. The general molecular formula for an unsaturated hydrocarbon can be represented as C n H 2n +2 .

An unknown compound A of molecular formula C10H18O reacts with H2SO4 to form two compounds (B and C)of molecular formula C10H16. B and C both react with H2 in the presence of Pd-C to form decalin. Ozonolysis of B forms D, and ozonolysis of C forms a diketone E of molecular formula C10H16O2. Identify the structures of compounds A, B, C, and E.

Compound A has molecular formula C7H15B.. Treatment of compound A with sodium ethoxide yields only one elimination product (compound B) and no substitution products. When compound B is treated with dilute sulfuric acid, compound C is obtained, which has molecular formula C7H160. Draw the structures of compounds A, B, and C.
